SPECIFICATION forming part of Letters Patent No. 467,057,01ated January 12, 1892.

Application filed August 27, 1891. Serial No. 403,908. (No model.)

To @ZZ whom it may concern.-

Be it known that we, CLARENCE SILVESTER and WINFRED S'ILvEsrnR, citizens of the United States, residing 'at Windom, in the county of McPherson and State of Kansas, have invented a new and useful lVindmill- Regulator, of 'which the following is a specilication.

This invention relates to wind-Wheels and more especially to the automatic regulators therefor; and the object of the same is to effect certain improvements in devices of this character.

To this end the invention consists in the construction hereinafter more fully described and claimed, and as illustrated on the two sheets of drawings, wherein- Figure 1 is a perspective view of a windmill with our improved regulator attached, the wheel being indicated in dotted lines. Fig, 2 is a front elevation of the regulator and the Atank full of water, the pump-rod being omitted to better show the parts. Fig. 3 is a transverse section of the regulator, showing the position of the parts just after the Wind-wheel has been thrown into the wind. Fig. 4 is a plan view of the regulator device, with the U-shaped pawl just commencing to engage the ratchet-wheel. v Fig. 5 is a detail View of the double segment, showin g one of its springactuated pawls or catches removed and illustrating the arm thereof as in position to keep the regulator-wire tight. Fig. 6 is a perspective detail 0f the shifting devices.

In the said drawings, the letter W designates a frame-work or tower supporting a wind-wheel. P is the pump-rod, reciprocate'd by said wheel for pumping Water into atank T, and the latter has a iioat F thereimwhich is connected by wires leading through abellcrank lever L with our improved automatic regulator, which is mounted on a cross-barC within the tower, all these parts being of the well-known and usual construction and forming no part of the present invention, except in so far as they are used in connection therewith.

The construction of our improved regulator is preferably as follows:

On a transverse shaft 1 is mounted a ratchetwheel 2, having projections 3 on one face, and 4 is a retaining-pand pivoted on an arch 4',

rising from the frame and preventing the backward movement of the wheels. 5 is a yoke pivotally mounted at its en'd on the said shaft and connected vat its center by a link G with the pumpfrod P, and 7 is a U-shaped pawl, 011e arm of which is vadapted to u'ormally engage the ratchet-Wheel, While the other arm is beveled, as at 8, the body of the pawl being pivoted in the yoke 5. Hence the reciproc'ation of the pump-rod will' cause the rotation of the ratchet-wheel in one direcl tion as long as the pawl 7 is in engagement therewith. t

Mounted loosely on the shaft 1 is a double segment whose hub has aiiange 10 and whose segment-faces 11 and 12 stand against the projections 3 'of the4 ratchet-wheel when the tank is vfull of water. In these segments are pivotally mounted catches 13, which are borne by springs 14 normally into position to engage said projections, although if the tips of the catches should strike the projections when the double segment is borne toward the ratchet-wheel the catches are permitted by their springs to yield, as will be clear. The segment-face 11 has a beveled corner 15, adapted to engage the bevel S of the U-shaped pawl, and this segment also has an ear 16, adapted to strike against some stationary member, as the support for the retainingpawl 4, to limit the movement of the double segment in what we will call its backward direction.

2O is a box projecting from the hub of the double segment, the front side of this box being open, and 21 is an arm pivotally mounted on a bolt 22 near the bottom of this box while its body is adaptedl to be connected therewith by another bolt 23, passing through the box near its outer end, as seen in Fig. 3. The regulator-wire R is connected to the outer end of this arm, as shown, and if such wire is slack, as is sometimes the case, the bolt 23 is withdrawn to allow the arm to fall slightly forward, so as to keep up the slack in the wire. However, the latter is preferably tight in a perfect machine and the bolt 23 should then beused.

Dian'ietrically opposite to the box 2O is a IDG small segment 25, mounted on and concentric i ment is a chain or rope 2G, leading to a weight 27. Vith this construction, when the double segment is turned forward by engaging with the ratchet-wheel, t-he arm 21 will be borne down until it strikes a cross-bar 21 on the frame, thus drawing on the regulator-wire R and throwing the wind-wheel out of the wind to stop its mot-ion in a well-known manner; but when the double segment is disengaged from the ratchet-wheel the weight 27 will turn it backward so as to raise the arm 21, slacken the wire R, and allow the wheel to move again into the wind.

The mechanism for moving the double segment longitudinally on the shaft is of the following construction: 30 is a bracketin which is pivoted the angle of a bell-crank lever 31, whose outwardly-projecting arm is provided with a weight 32 and whose downwardly-projecting arm is connected at its lower end, as by a wire 33, with the tloat F in the tank T through suitable connections L, as shown. 34 are two arms pivoted at 35 to the depending arm of the lever 3l, extending thence through the bracket 30, turned down, passing loosely around the hub of the double segment and connected, as at 36, beneath said hub, and 37 is a finger, whose body is bolted between the arms 34 and whose tip stands against the outer face of the flange 10. By this means, when the tank is full of water the wire 33 is slack and the weight 32 has caused the shifting devices to move the double segment toward the ratchet-wheel, as seen in Fig. 2; but as the lioat descends with the falling of the water in the tank the double segment is drawn away from the ratchet-wheel, as will be u nderstood.

The operation of this device is as follows: The wheel being in motion and the pump-rod P reciprocating when the tank has been lled, the double segment will be at the position indicated in Fig. 2, and at this time the beveled corner 15 of the segment-face 11will be moved under the bevel 8 of the U-shaped pawl 7. The latter is thus permitted to fall against the ratchet-wheel, and the reciprocation of the pump-rod then turns the ratchetwheel forwardly, as above described. As the double segment is at this time connected with the wheel, it also turns forwardly, raises its weight 27, draws downwardly on the arm 21, pulls on the regulator-wire, and throws the wheel out of the wind, The latter result of course checks the reeiprocation of the pumprod and cuts off the flow of water to the tank, which is now full; but it often occurs that the wheel will make several revolutions at this time through its momentum or from other causes. lVhen .the double segment is thus in forward position, its rear segment-face 12 stands under the U-shaped pawl 7 and holds the tip of this pawl out of engagement with the ratchet-wheel. Hence a few additional revolutions of the wind-wheel will not turn the ratchet-wheel and segment farther for ward and will not draw any farther ou the regulator-wire. Vith the parts in this position, supposing the water to be drawn out of the tank, the float F will fall and the bell-crank lever 31 will be turned by the wire 33, and this motion will draw on the shifting devices and slide the double segment on the shaft until it is completely disengaged from the ratchet-wheel, when the weight 27 will cause it to turn backward to its original position until its ear 1G limits its further movement and the regulator-wire is thereby slackened, so that the wind-Wheel resumes its rotary motion, the pnmprod is reciprocated, and the tank is gradually filled. At this time the segment-face 11 will hold the U-shaped pawl completely raised, as seen in dotted lines in Fig. et; but as the lioat rises this segment-face will slowly move to the full-line position in this ligure, at which time the engaging-bevels will allow the tip of the pawl to engage the ratchet-wheel, as shown. During any of such motions of the double segment the regulatorwire will be drawn on only when the arm 2l turns around its pivot and strikes the bottom of the box 20, and hence if this wire becomes too slack it should be tightened, as will be clear.

lVe do not limit ourselves to the precise details of construction, as considerable change may be made therein without departing from the spirit of our invention.
